NON-REFILLABLE BOTTLE.

SPECFIGATION forming part of Letters Patent No. 569,778, dated October 20, 1896.

application led February 8, 1896. Serial No. 578,508. (No model.)

.To all whom it may connerie:

Be it known that I, PATRICK WILSON, a citizen of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Non-Fillable Bottles, of which the following is a speciiication, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in non-iillable bottles, and has for its object the provision of new and novel means whereby a bottle cannot be refilled or again used when once emptied.

The invention has for its further object to construct a bottle of the above-described class that will be extremely simple in its construetion, strong, durable, effectual in its operation, and comparatively inexpensive to manufacture.

A still further object is to construct an interior or valve portion in such a manner that the same may be used any number of times after the bottle is broken and the valve removed therefrom.

W'ith the above and other objects in view the invention finally consists in the novel construction, combination, and arrangement of parts to be hereinafter more specifically described, and particularly pointed out in the claims.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this speci tication, and wherein like numerals of reference indicate similar parts throughout the severa-l views, in which- Figure l is a front elevation with a portion of the neck in. vertical section, showing the valve in position. Fig. 2 is a vertical sectional view ol the valve. Fig. 3 is a cross-sectional view of the valve, taken on the line XX of Fig. Fig. 4 is a plan view of the washer. Fig. 5 is a side elevation of the lap-valve- Fig. G is an underneath plan view of the valve. Fig. 7 is a top plan view of the same.

In the drawings, l indicates the neck of the bottle. 2 represents an interior annular flange arranged near the upper extremity of the neck. 3 represents the lower flange arranged a short distance below the iiange 2.

The valve l is placed in the neck of the bottle underneath the interior annular flange 2 and rests on the ange 3. This valve el is provided with a head 5, having apertures 5 around the same, all leading to the center hole in the valve, and the valve is further provided with a groove 6 between the head and the body portion of the valve to receive a washer 7 At the base of the valve a is provided a rubber Hap-valve 9, which rests on a circular plate 8, secured at the base of the valve. The flap-valve may be composed of rubber or any suitable material, and is fastened at one side, while the other is left loose, allowing the liquid to force the same upward when the pressure is on the underneath side.

In the side of the valve a is provided a groove or slot 10, forming an air-inlet, and apertures l1 are provided near the edge of the washer, and airholes l2 l2 are provided at the bottom of the body portion of the valve.

The operation of my improved non-refillable bottle is as follows: When the bottle has been filled, the valve a is inserted in the neck and will rest on the flange 3, as is shown in Fig. l of the drawings. The rubber ring or washer is then placed over the head of the valve and forced over the same, when it will engage in the groove 6 and be retained rigidly in position, and will also prevent the withdrawal of the valve, as the rubber ring would engage on the fiange, making the opening too small to withdraw the valve. When it is desired to empty part or all of the contents of the bottle, the same is tilted, as in the ordinary manner, and the pressure on the bottom of the flap-valve will force the same toward the top of the bottle and allow the liquid to flow through the valve and out of the small holes in the head of the same, from whence it will pass ont of the mouth of the bottle.

It will be observed that it will be impossible to pour any liquid into the bottle after the valve has been placed in its position, as the weight of the liquid on the top of the fiapvalve will force the same down tightly over the port of the valve 4.- and prevent the liquid from entering the bottle. Neither could the bottle be iilled under pressure, as the increase in the pressure would act in the same man ner as heretofore described, only to a much greater extent. The air-holes provided in the washer will admit of sufficient air to pass TOO into the valve through the slot 1') to allow of the easy and rapid outow of the liquid.

By this Construction of a non-refillable bottle it will be necessary to break the neck of the same in order to remove the valve, thus destroying,` the bottle, but the valve may be readily inserted in a new bottle by the manufacturer and used again, but this cannot be done by any one else, as the original bottle is destroyed,

The rubber flap-valve may be weighted on its free end, if desired, which will help to return the same to its normal position rapidly when the bottle is righted. I do not Wish to limit myself in the construction of this valve to any particular material, as the valve may be made of brass or other metal, and the eireular plate S of hard rubber or metal, or both may be made of glass, but the ring 7 and the nap-valve are preferably Composed of a flexible material.

It will be noted that various changes may be made in the details of construction of my improved non-rellable' bottle without departing from the general spirit of my invention.

Having fully described my invention, What I claim as new', and desire to secure by Letters Patent, is-

1. In a bottle, a neck portion having interior flanges a valve resting on the lower of said flanges, said valve being composed of any suitable material, and having` a plate at its lower extremity carrying a rubber Washer forming a ap-valve over the aperture in the plate, said valve being also provided With a slot in the side and holes in the base for airinlets, substantially as shown and described.

2. In a bottle, a neck portion havingr inte rior ianges a valve resting,` on the lower flan ge havin g a rubber flap-valve arranged at its base, and a washer over the head of the valve, said Washer having' air-holes, and the valve bein g provided with a slot in the side and holes in the base forming; air-inlets, substantially as shown and described.

In testimony whereof I affix my signature in presence oi' two Witnesses.

PATRICK XVILSON.
